Enhancement of output power level of RF energy harvesting circuit using Wilkinson power combiner

Abstract

ABSTRACT Different interesting research has been going on in the area of RF energy harvesting during the last decade. This paper presents the comparisons of different Schottky diode-based RF energy harvester circuits and cross-coupled MOS-based RF energy harvester circuits. An improvement at output power level is achieved. In this proposed work, the author has proposed a simple two-way Wilkinson power combiner to connect with these RF energy harvesting circuits for achieving a higher power level. The experimental output voltage of a three-stage diode-based Villard RF energy harvester circuit has been carried out. A Schottky diode-based Villard RF energy harvester circuit is tested at 600 MHz, and output voltage has been carried out. The circuit is also connected at 2.4 GHz Wi-Fi. A Monte Carlo simulation was also carried out to analyse the output parameters obtained from this proposed MOS-based circuits.
